IMPROVEMENT IN REPEATING FIRE-ARMS.

Specification forming part of Letters Patent No. 92,969. dated lebt-nary15, 1&39.

To LZ whom it may concern: l

Be it known that we, HENRY H. MCKENNSL and FREDEREG GorH, of Biddefordin the county of York and State of Maine, have invented a new and usefulGun or Improvement in Fire-Arms, and we do hereby declare that the sameis fully described and represented in the following specification andthe accompanying drawings, of which- Figure l is a top view, Fig. 2 sideelevation, and Fig. 3 a longitudinal section, of a fire-arm constructedin accordancefwith our invention. Fig. et is a transverse section of it,the same being taken through one of ithe strikers and its nipple. Fig. 5is a top view of the lockcase and operative parts Within the same, asthey appear when detached from the barrel. Fig. Gis a separate top viewof one of the sears.

In such drawings, A denotes a gun-barrel, while B is the stock thereof.The said barrel is furnished with two vents or primingnipples, c b, oneof which is arranged in advance of the other, and both xed inthe'side ofthe barrel and with respect to its breech, as shown in the drawings. Itis intended that the fire-arm shall be capable of discharging twocharges or loads in succession, one being placed on top of the other,and the latter serving as a breech to the former, which is first firedor discharged.

In loading the piece we generally employ circular felt or pasteboardgun-wads, one of which we arrange between the two loads and over theball or shot of the rearmost one,- so as to prevent discharge of thesaid rearmost load by the ring of the foremost load. The lock we arrangeunderneath the gun-barrel, its case being shown at C, and we provide thesame with two hammers or strikers, D E, arranged to work transversely ofthe barrel and against the nipples, respectively. Each of the hammers,formed as shown in Fig. 4, turns on a fulcrum, c, and is actuated by twomainsprings, ef, which are arranged at right angles to one another andwithin the lockcase, as shown in Figs. 3, 4, and 5. Each hammer orstriker operates in connection with aleversear, g. (Shown in top view inFig. 6, in section in Fig. et, and in dotted lines in Fig. 5.) This searturns horizontally on a fulcrum, h, and

has its longer arm pressed toward the notched part fi of the striker bya spring, k, arranged in the lock-case, as shown in the drawings. Theshorter arm of the sear extends directly in rear of a projection `orshoulder, Zor m, formed on a trigger-slide, F, arranged as shown inFigs. 3, 4., and 5. The said trigger-slide is constructed in two parts,a 0, which are formed to lap and lock on one another, as shown at p inFig. 3. This enables the lock easily to be detached from or applied tothe barrel and trigger when necessary. The rear part. a, of thetrigger-slide is so connected with the single trigger G as to be capableof being retracted .with the said trigger G when the latter is drawnbackward, a spring, r, serving to move forward both trigger andtrigger-slide. When the hammers are set at full-cock, a single re-`traction of the trigger will cause both of them to fall or to bedischarged toward their nipples or percussion-caps thereon, and in suchmanner that there will be a short interval of time between the fall ofthe forward hammer or striker and that of the latter, such beingoccasioned by reason of the arrangement of the two shoulders Z m withrespect to the sears.

rPhe rearmost shoulder is placed a short distance from its sear when theforemost shoulder is in direct contact with its own sear, such distance,while the trigger-slide is being retracted, being sufficient to producea discharge of the foremost striker a short interval of time before thatofthe rearmost one may be effected, such interval being sufficient forthe discharge of thekforemost load of the piece before that of the rearload may take place.

The advantages of this fire-arm over an ordin nary double-barrelgun,particularl y for a rapid discharge of two loads in succession, willread,- ily be seen by Sportsmen or others skilled in the constructionand use of fire-arms.

By not only making the lock-case separate from the barrel, and soapplying it to the underside of the same that it may be placed againstthe same, fastened thereto by one or :more screws, s, (see Fig. 3,) butby constructing the trigger-slide in two parts, so as to lap and lock onone another, as described, we are enabled to easily detach the lock-caseand lock from the barrel at any time, as well as to subsequently applythe same to the barrel and the trigger7 so as to cause the latter to bein its proper connection with the lock.

By having one hammer or striker to operate or be discharged before theother, the rear charge may be red at any interval of time afterdischarge of the foremost one7 and the gun may be used for ring singlecharges Whenever it may be desirable so to do.

We do not claim a lire-arm constructed not only with its nipples orprimers arranged one in advance of the other on the barrel7 but With alock having a hammer or striker to operate with each nipple or primer;but

XVe claiml. The combination of two strikers7 one trigger, and amechanism which Will not only enable each striker to be set to andmaintained at full-cock, but by retraction of the trigger will causeboth strikers, when at full-cock, to be discharged or set freeconsecutively, so as to be forced against their respective nipples orthe percussion-caps or priming thereon, or the equivalents of such, andcause explosion of the priming of the charges in the order as specified.

2. The above-specified application of the lock-case with respect to thebarrel, in combination with the construction and arrangement of thetrigger rod or slider. in separate parts and in such manner as to becapable of being locked together, and of being` unlocked or disconnectedunder circumstances as specified.

3. The application and arrangement of the two mainsprings of eachstriker in the lockcase, as explained.

4. The combination of the trigger-slide F and lever-sears, arranged andoperating with respect to the two strikers as specied.

In testimony whereof We have hereunto set our signatures. v
